It’s always difficult to accurately predict an upcoming product based on rumors and leaks — though some were spot on, like all the HTC One M8 stuff we’ve seen, which turned out to be true — especially if that product is an upcoming Apple product. We’ve seen Apple, as a company, turn from the most secretive into the maker of probably the most leaked phone (the iPhone 5s), and the speculation continues with chatter about a 4.7-inch and a 5.5-inch iPhone.

Reuters’ supply chain sources claim that production for the screens of the 4.7-inch variant might start as early as next month (May), in order to get everything ready for the fall launch. Said sources also claim that the 5.5-inch version could be delayed, and have it on good authority that the makers of displays will be Japan Display Inc, Sharp Corp and South Korea’s LG Display Co Ltd.

Because of technology and production restraints, the 5.5-inch product might be delayed, and could use film sensor technology instead of in-cell technology (currently on the iPhone 5, 5s, and 5c) that allows for thinner overall construction.
